Do you know why the coolant put in the car is of different colors?
Coolant is put in the car to protect the engine from overheating, but its color is not just a decoration, but an indication of its chemical composition and technology.
Main coolant colors and their meanings:
🔹 Green: The oldest and most common coolant, which is made of silicate-based inhibitors. It protects the engine from rust and corrosion.
🔹 Red/Pink: OAT (Organic Acid Technology) based coolant, which has a life of 5 years or more.
🔹 Orange: OAT coolant based on Dex-Cool technology, which is used in GM vehicles.
🔹 Blue: Popular in Asian car brands like Honda and Toyota, it is also OAT based.
🔹 Yellow/Gold: A coolant with hybrid technology that contains both silicate and organic acid.
⚠️ Important warning:
Never mix coolants of different colors. Their chemical composition is different and incorrect mixing can cause serious damage to the cooling system. Always use the coolant recommended by the vehicle manufacturer.
